Oh, and I don't even want to research this myself, I want others to do the work ... for free.
Thats a bit unfair. I had a need to convert some output into PDF a while back and started looking thru the many proprietary and open source options, and there were a lot to choose from. It was awfully hard to determine which were quality and which weren't. Installing and trying to program a working solution against each API would have taken up a huge amount of time. There is nothing at all wrong with asking if others have been thru some of that process and found a favorite. I certainly would have liked to see some comparisons or good product reviews to help me decide.
Also, one thing I started to suspect; a number of the supposedly proprietary PDF tools and API's that I investigated appeared to just be a GUI and some wrappings around a GPL PDF library, usually Ghostscript, with little or no attribution given. Once again, there is nothing wrong with asking for other peoples experience with these tools and libraries; you don't want to find out you have breached GPL licensing AFTER you have created your solution, do you?
